JEAN ARMAND GALLAUD, (iF N AN'IES, FRANC.

Letters Patent No. 96,399, (Intell October 26,. 1869,4 poten fm1 in France, Muy it), i858.

The Schedule referred to in these Letters Patent and making part f the same To all whom fit 'may concern Be it known that 1, .l1-:AN Ammsn CALLAUD, ot the city of Nantes, in the ilmpirc of France, have invented a nsct'ul Improvement in the (lalrnnic Pile or Battery; and "I do herebydeclarc the ibllowing to be a true, full, and exact description of the. same, rcterence being had to tho aecon'lpanying drawh'lgs, making' a part. of thislspccitieation. A

The nature of my invention consists in providing a battery ot' such form and proportions of the materials used, as to operate in the .mostrapid manner, havingr the parts so constructed as to he easily supplemented when desired, andnot liable to be disarranged by the I ordinary uses ofthe same. y. p

Figures 1, 2, 3, and 4, represent the dittlfrent parts of this, my` invention, in which- A represents an exterior cup, ot glass or analogous material, four and three-quarters inches in height, and

Afour inthes in diameter. y

B is the zinc plate used,i and placed rertically within said cup, and one and one-quarter inch in height, three inches in diameter, and tliree-eighths of an inch thick, and presenting:r twenty-two and one-half inches of surface to the fluid contained within the cup. This zint` can be made of sheet-metal or cast. When made of the latter, it made thicker at the base, so as .to enable it to bc easily drawn from the mould, and to present the greatest surface when the metal is most.

. exposed to the dissolving-solntion.

1n the sheet-zinc, two copper hooks, b b', are riv-` eted and soldered. In the cast-zinc, similar hooks are placed in the mould, and the meta-l poured around 1hem, by which hooks the zinc is suspended from the glass in t-l|e.solution.

lhe copper rod o is also soldered 4or cast to or upon :the zinc rei'errcdto, extending over the glass jar on `which it rests, and curved downward into the next jai, m the maman-.shown in tio'.

This rod c is covered by :Vrubher tube, E, to the ertent of its length that is exposed to the solution, to prevent the precipitation ofthe copper.,

To the end ot' this rod 0,:1 sheet o1' copper, I). is atu ened,` and wound sl'iirallyaround its centro. ".lhese copper rods exposed to the. air, au` turned, to prevent the action of the salts uponthem` and the colmcrhooks b' b' are painted. y

'.lhe rubber tube l},-wvering' the rods c, is li'rmly and securely tied or bound, at either cud, to therod.

To prepare this battery for action, t'rom one to two. ounces of sulphate of copper are put' into the glass, and enough water poured in to innnerse the `/.inc. lt' an immediate current is desired, add to the'water a small quantinrot' sulphate ot' zine, or mok-salt, or a t'ew drops ot snlphurio acid.

It' it is desired' to start the battery with a prepared solutionot copper, first till the jars with ,pure water to the height ot' the lower part of the suspended zinc, and through a funnel, the lower end ot' which reaches to the bottom of the glass, and pour in the solution of copper, which, from its greater density, will cause the pure water to rise above it, itsell' remaining at the bottom ot' the glass. l

A battery arranged in this way will work as long,r as the zine lasts, and as long as the liquid is saturated with the sulphate ot' copper. This saturation is easily maintained by dropping, from time to time, some orysta-ls aml sulphate ot' copper into the jar, which, by graduallydissolving, keeps the liquid constantly saturated.

What l claim as .my invention, and desire to secure by Letters Patent, isv 1. The combination-and arrangement ot' thc jar A, zinc B, hooks b' bf, rod c, rubber tubing E, and sheet-- copper 1'), in the manner and t'orthe purpose herein described.

2. The combination and arrangcmcntoi' the devices above rncntionedfin the form and prrmortions herein described. f i' This spccitiration signed hymn, this'l4th day ot' January, 186i. V
